The system boots to a graphical desktop (MATE + LightDM) and works fine until I open a program with the discrete graphics (DRI_PRIME=1). Going to bisect once I get the laptop later in the day. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
